Embodiment 1

[0034] When the key card is recharging the key pool, the key management server will assign a group identity to the key card and give it an ID within the group. The key fob will be written into its own private key key pool and the public key key pools of other groups within the group. When the key management server establishes a group of an asymmetric key pool system, it will generate a corresponding number of private key key pools according to the number of members, and at the same time generate a public key key pool corresponding to the private key key pool one-to-one . The private key key pool is composed of true random numbers of a specified length. The public key key pool is composed of public key data, corresponding to the private key in the corresponding private key key pool.

[0035] The method of generating the public key is the calculation method in the DH key exchange algorithm. The key management server defines a large prime number p and a number g, and g is the ...

Abstract

The invention relates to an anti-quantum-computing key negotiation method based on asymmetric key pools. The method includes a group. The group includes a plurality of use ends. The key pools are stored in quantum key cards configured for all the use ends, and include private key pools of the current parties and public key pools of the other members of the group. Equal negotiation keys are obtained through interaction of parameters of all the parties and the key pools of the current parties, and then key negotiation of every two terminals is realized. The quantum key card are independent hardware isolation equipment, greatly reduces possibility of stealing the keys by malicious software or malicious operations, and also cannot be obtained and cracked by quantum computers; and in the group,an asymmetric key exchange manner is adopted to realize key negotiation between objects, key sharing of two communication parties is realized, other objects cannot get corresponding shared keys, andcommunication security of the two communication parties in the group is guaranteed.

Description

technical field [0001] The invention relates to a public key cryptosystem and an asymmetric key pool technology, and specifically relates to the key exchange algorithm. The present invention is to realize the key exchange technology between communication parties in a group. Background technique [0002] The rapid development of the Internet has brought great convenience to people's life and work. People can sit at home to send and receive e-mails, make phone calls, conduct online shopping, bank transfers and other activities through the Internet. At the same time, network information security has gradually become a potential huge problem. Generally speaking, network information faces the following security risks: network information is stolen, information is tampered with, attackers fake information, malicious damage, etc. [0003] At present, the key technology to ensure the security of network information is cryptography. In the field of cryptography today, there are mai...
